I'm sorry you have not had luck in contacting me. The site you have referred has been rather poorly administered. Thank you for your message. I'll remove the link connected to you. I have copied a formula from your page as an image. Can I still use it ? I liked the style of it and I would be pleased, if I could still use it without connection to you. The page has been built for the students of University of Turku, Finland years ago. That's why the old style. It seems that the page still has some value. I know it is hard to read the text written in Finish, but I can assure you, the text has been written with positive attitude. It is nice to see that our pages have been seen, if only with some Google robot ;) I do understand your situation. Please check, if the page is OK now and tell me, if there is something I can do. Personally I'm rather interested in human environment and effects of humidity in buildings and computer interfacing to collect data about humidity in various environments. So I appreciated the data I got from your old pages. Thank you. Have a nice day. 02jul2015 PTM
